Products

Ferrosilicon for steel

A wide range of ferrosilicon alloys are available for alloying and deoxidation purposes in steelmaking processes. Elkem supplies ferrosilicon to the steel and steel related industry. Ferrosilicon is an important additive in the manufacture of steel products. Our main markets are the worldwide producers of alloyed, stainless and carbon steel, as well as the producers of manganese alloys.

Iron foundry products

Elkem manufactures a wide range of inoculants, MgFeSi alloys and preconditioners for the production of cast irons. Alloys are available from the extensive portfolio to cover all foundry conditions and iron qualities.

Recarburisers

Recarburisers are used in high-grade steel, grey and ductile iron castings. Elkem’s Elgraph® recarburisers has proven to give the best performance on dissolution rate, carbon recovery and with the lowest nitrogen/hydrogen content. The unique production technology, located in Norway, is the foundation for the high quality carbon additives.

A windmill hub producer had scrap issues due to poor Charpy impact results. The problem was related to the charge materials and nucleation state of the base iron. The solution was to replace their current preconditioner with a specialist alloy, Preseed™ preconditioner. This resulted in 50-75% increase in Charpy impact results and eliminated metallurgical scrap.

Elkem’s experienced technical staff can help you resolve the issues, and find cost effective solutions.

The use of thermal analysis to determine the nucleation levels in base iron is becoming more common in foundries. Taking corrective action at an early stage of the process can reduce scrap, and save time and money downstream of the furnace.

Epic™ is a portable, affordable and user-friendly thermal analysis system designed to give information and control of the process from the furnace to the mould, quickly identifying any areas that need attention before problems arise.

Elkem’s experienced technical staff can help you pin point causes of variation, and find cost effective solutions.

Titanium, aluminium and moisture are the common causes of hydrogen pinholes in greensand systems. Both Al and Ti lower the surface tension in the liquid iron and that allows gasses to be more easily picked up.

Elkem produces a range of MgFeSi alloys and inoculants with very low Al to help keep the aluminium content below the critical levels for pinhole generation.

Selection of good quality charge materials for melting stock makes production of quality irons easier. However, many foundries are limited to what is available. Zinc plated steel, for example, creates both environmental and metallurgical issues.

Using Preseed™ preconditioner can allow for full or partial replacement of expensive pig iron with more cost effective solutions.

Elkem is working with foundries to develop solutions for these and other charge material related issues.
